Become Stronger by Slaying Demons, Starting from Holding a Knife

Kill demons and gain longevity, which can be used for practice and deduction. Zhou Yin is a mere mortal with a lifespan of less than a hundred years and no long-term possessions. In troubled times, they are just fish and meat on the chopping board, and they are destined to die without rebirth. Fortunately, you can gain longevity by hunting monsters, and since then you have embarked on a path of cultivation where monsters eat people and he eats monsters. Many years later, he looked down upon the world, eating dragon liver, phoenix marrow, delicacies from mountains and seas all over the world. Looking far into the sky, I heard that at the end of the world, in the Immortal Palace in the distant sky, there are already thousands of demons, each of whom has experienced endless years. This trip to heaven is nothing more than to borrow tens of millions of years of life from you to prove my great path!
